/ Application filed September 18, 1926, Serial No. 136,328, and in Germany June 10, 1925.

In using the different founts of type of the monotype system, it is necessary to punch different combinations of holes in the paper band for the same letters, in order to ensure thelett'ers occupying the proper position in the standard line. Up to the present, this has entailed the use of different intermediate frames. J

The invention enables a' single intermediate frame to be used for all founts of type, inasmuch as it renders possible a change of position of the combination-bar strikers that effect the opening of the air valve, said strikers being, according to the invention,

. adjustable in the longitudinal direction of the bar.

This results inv economy because only a single intermediate frame is'now required whereas it was necessary heretofore to keep a large stock of intermediate frames.

Various devices may .be employed for carrying out. the invention, some embodiments of which are illustrated, by Way of example, on the accompanyingdrawings to I which reference will now be made.

' Fig. lis a perspective view of the usual intermediate frame of the mon'otype machine;

Figs. 2-4, 5-7, 8-10 and 11-14 show different ways of attaching the strikers.

In Fig. 1, a denotes the key knob which is struck by the compositor in order to punch the hole in the justifying strip for a letter. The stroke turns the key lever on the pivot b so as to make contact with the nose 0 of the combination bar at. This causes the bar 0? to slide and the strikers g to actuate the rocking levers e, f, which are pivoted at e. The movement of these rocking levers e, f actuates the valve rods h, 72., through the cross bars 11, and applies pressure tothe air valves j, whereby air is admitted from an air chamber to the piston,

which thereupon forces the proper punches combination bar on amuch enlarged scale. F g. 3 a side elevation of the striker, and F 1g. 4 a vertical section through said striker) the striker g is provided with an extensionweb g"adapted to be inserted into milled dovetail slots d inthe combination bar (Z. In order to afford the striker a secure hold, its Web 9 is slightly dented at g and the slots cl are provided with holes (Z so that, when the web g is slipped into one of the slots d, the projection g is able to snap into the corresponding hole d thus producinga kind of press-button fastening, that prevents the striker from getting loose by accident. To give a still further hold to the striker, a slight bulge is produced on the web 9 at the point 9 the ends of which bulgeset up a clamping action between the web and the edges of the dovetail.

In the embodiment according to Figs. 5-7 (of which Fig. 5 is' a perspective view of part of the combination bar on a much enlarged scale, Fig. 6 a side elevation ofthe striker, and Fig. 7 a section) the striker g is connected,,by means of an integral web 9 with an extension disc 9 which is about double the thicknessof said web 9 the latter being of the same thickness as the striker proper. Gaps (Z and d corresponding respectively to the web 9 and disc 9 are cut in the bar (i, so that the striker, as shown in Fig. 7 fits into the bar and lies flush with the same on both sides.

Another embodiment is illustrated in Figs. 8-10, of which Fig. 8 showsa perspective view of a portion of the combination bar on an enlarged scale, Fig. 9 a perspective view of the striker, and Fig. 10 a cross section through the bar and striker. In this case the striker g has a thin extension strip 9 to which is attached a bracket member 9 so as to form a U or stirrup and thereby enable the striker to be slipped on to the bar d from below and ride thereon. To prevent the striker from slipping down off the bar, a press-button type of catch d d similar to that of the embodiment according to Figs. 2-4, is provided on both sides.

Still another embodiment is shown by Figs. 11-14, of which Fig. 11 is a perspective view (partly in section) of a portion of the combination bar, Fig. 12 a plan of the bar, Fig. 13 a view of same from below, and Fig. 14 a cross section. The combination bar 03 is hollow in this instance, so that the striker 7 can he ndjustehly arranged in the resulting cavity and adapted to he secured sit the desired points. As shown, the nose g has on extension 112. in the form oi a guide hloek. The upper ihiee ot the her (Z is provided with holes 0Q and the under side oi? the her is provided with wider and narrower shits it. .r. the Wider ones 8 heing to zirconinlodete the striker.

in order to adjust the striker g and secure it iljlfziili. :iii that in needed is to pry the sides of the her (3 epzirt hr means. for example, of it tooi ina led in the slot ii, whereupon, :i'iter pushing down the ing 0, the striker g can he detnrhed :ind inserted in another oi? the sdoin in the log 0 tittingr into the cone spending hole 0 in the her (Z, ihns supportin the Siili li' on nil sides.
